To all 'whom t may concern.' v

Be it known that we, FREDERICK T. voN VAHLDE and FRANK ARNOLD S'rrENs, citi- Zens of the United -States, and residing at St. Bernard, inthe county of Hamilton and State of Ohio, have invented a new and useful Improvement in Can-Labeling Machines, of which the following specification 1s a full disclosure. c

Our invention, relates to a can-labeling machine, and in particular to the means for applying a coating or stripe of glue completely around the periphery of the can before applying the label.

An object of the invention is to provide a,

can-labeling machine with simple 'and elficient means for applying a coating or stripe of glue or :adhesive upon the can periphery and entirely around the same and at the cover joint of the can, whereby a label can be secured to Aand around the can for covering and hermitically sealing the cover joint.

Another object of the invention is to lpro-l vide a can-labeling machine with a rotating glue distributing roll, adapted to be engaged by a can, together with means for holding the can at such roll engaging point or glue applying station and rotating the can while in contact withsaid gluedistributing roll.

Another object of the invention relatesV to the combination of belt can: conveyer means arranged to engage and advance a can over a track .upon a glue distributing roll for applying a coating of glue to the periphery of the can, and a stop ldevice forr holding the can at its gluing or pasting station, releasing by a successive can advance toward the gluing or pasting station. n

Further objects and features/some relating to structural details, will definitely ap'-` dealer to a user. Thecovers or caps of such packages or lcontainers arer'sealed andsef cured to the body ofthe container by a label or wrapper. To make a hermetic seal around the cover joint, it is necessary to gum or paste the label entirely around the periphery of the can and cover flange. iSuch method, aside Vfrom making a ysecure and tight closure, serves as a safety measure against fraud Vby refilling, as it requires theY label to bereut, or seal broken, before the cover can be removed. The usual method of, opening is to cut the label around the can at the edge of the cover fiange. Therefore as the entire surface of the label or, can around the cover joint is required tog'be, pasted orgummed to makek a seal as ref quired, commercial, can-labeling machinesv could not be used for the work, as such machines are adapted for spot pasting: or gum# ning the can and cross edgeV pastingv vthe abel. lVith our invention a commercial canlabelingmachine is available for the diHerent methods of applying an adhesive, above mentioned, and as the gluing mechanism only is herein concerned, a complete'structure of the can-labeling machine is not eX- hibited in the views, andonly jso much of the structure is shown as will suffice to illustrate the connection of the invention there-4 with, thus the label feeding and label cross, edge pasting devices are eliminated from the drawings. Y l l Referring to the drawings, l indicates a skeleton frame structure upon which the various devices of the labeling machine are supported and secured, Vand includes the horizontal frame beams 2 as a table. A pair ofbow-end supports 3 are fixed to each end of` the frame beams `2 projecting upwardly and inwardly, and the free end of each of said bow supports has a vertically slotted lug 4, to which the brackets 5 of the carrier frame 6 are adjustably secured. Each end of the carrier frame 6 respectively provides journals for the shafts 7, said shafts each carrying a pair of pulleys 8. The pulleys:8 on each shaft are appropriately spaced from each other and in alinement with a com-f panion pulley at the op'posite'end of the carrier frame, for respectively tracking a pair of can conveyer belts 9, 9. The Vbelts 99, are spaced to bring'their belt runs uponv and in frictional engagement with the opso.l

posite edges of the cans for conveying and rolling the cans from a feeding end to a discharge end upon a pair of track rails 10, 10, running longitudinally with and above the horizontal frame beams 2. he spacing gage of the track rails are such a distance apart so as to interveningly receive the can gtmm'iing roll and labels. A can end guard rail 11 extends longitudinally above and parallel with a relative track rail 10 for guiding the cans in their travel through the labeling machine. 12 indicates a can holding delivery tray disposed at an incline, at the receiving end of the machine, and 13 indicates a tray at Ythe. discharge end of the machine. The traysY 12 and 13 are each hinged to a bracket fixed to a respective bow support, adapting the trays to be swung downwardly when not in use. The labels 14E in a stack, are supported upon the table 15 between the track railsy 10, 10. The table is appropriately raised by ratchet feeding mechanism operating at timed intervals with the release of each can from the delivery tray 12, as the can starts in its travel to be labeled. The table is elevated or fed upwardly to always bring the uppermost label of the stack to an elevation to be picked up and wrappedaround the can as the can rolls over the label. The feeding mechanism being separate and apart from the invention herein, no disclosure thereof is made, as the same may be of a construction well known and common in the art.

The parts of the machine heretofore described are all substantially the same as those in an existing commercial machine, and, therefore, may be regarded as of old structure, with the function and operation' well-known, the introduction thereof as herein made may be regarded as suiliciently clear and ample for the purposes herein required, and it may also be understood that suitable power means are provided for transmitting motion to the carrier belts 9, S), through one of the shafts and pair of pulleys 8.

0cm. gluing mechanism.

Below the rails 10, 10, in advance of the label table, a paste or glue holding reservoir 16 is supported upon the frame within which a glue applying or distributing roll 17 is revolved. The glue or adhesive distributing roll 17 has its periphery provided with a series of annular grooves and thereby forms a series of spaced annular ribs which engage with and distribute the glue upon the periphe 1y of the can 1S diametrically disposed above the roll 17. A peripherally grooved or ribbed roll avoids an application of an excessive quantityV of glue upon the can periphery, and represents a preferred tyipe of roll, although its peripheral surface may follow various designs of ribbing or roughening most adapted for efficient distributing or spreading of the glue upon the can and which will apply the glue around the can at the cover joint for effectively securing the label to the can over the cover. ln fact, the glue distributing rolls now commonly employed in the con'nnercial can-labeling machines can be used.

The can after it has been released from the delivery tray 12 by time controlled delivery mechanism, not shown, or as it may be manually released by the operator, travels by gravity forwardly over the rails 10, 10, until it is engaged by the lower forward runs of the carrier belts 9, 9, from whence it is conveyed or rolled by belts through their frictional contact upon the peripheral edge of thecan. The can continues in its travel upon the rails until it strikes against the stop arm 19 on theprock shaft 2O journaled in bracket journals depending from the carrierframe. The stop arm 19 is located at a point or station in the can travel which will hold the can diametrically above and upon the glue distributing roll 17. The

periphery of the glue distributing roll 17 friction impartingV a force counter to thev direction of the can rotation and also increases the frictional grip between the can and belts for revolving the can upon the rotating glue distributing roll. The glue distributing roll likewise is rotated in an appropriate direction to assist, with the belts, in transmitting rotary motion to the cans, although rotating at a dierent rate of speed from that of the belt, which produces a wiping action upon the can periphery as may be distinguished from a rolling action, one with the other, for the purpose of depositing a thin film of glue upon the can. This differentiation in speed offers a control as to the quantity of glue applied to the can. The carrier belts 9, 9, at points in front and in rear of the can gluing station, travel over guide rollers 21, 21, respectively journaled upon journal brackets 22, 22, depending from Vthe carrier frame. These guide rollers permit such portions of the belt therebetween to be spanned when engaged by a can to increase its frictional grip upon the can.

As shown in the drawing, the belt is spanned to such a degree, so that such portion of the belt extending beyond the can edge will lap over and against the ends of the can, exerting an increased force, and together with the opposite belt operating similarly, impart a compressing infiuence against the' can ends, tending to force the cover upon the can body before the label is applied.

The glue distributing roll 17 is mounted upon a shaft or spindle 23, suitably journaled with the side walls of the glue reservoir. On one end of the shaft 23 a pulley 2a is xed, which pulley is engaged by a belt 25 engaging with a pulley 26 xed on a shaft 27 journaled in the carrier frame. Y The shaft 27 is provided with a second pulley 28 engaged by a belt 29, and the belt 29 is engaged over a pulley 30 fixed upon the shaft 7, for the carrier belt pulley.

The can after its periphery has been suitably coated with glue, and after it has made one complete revolution at its gluing station, is released by raising the stop arm 19. The arm 'is automatically raised by asuecessive can advancing toward the glue roll and through the following instrumentali' ties 32 indicates a lever arm fixed on the rock shaft 20 and pivotally connected Ywith a link 33. The link 33 extends forwardly and pivotally connects with a lever arm 34 fixed to a rock shaft 35, journaled in the bracket 3G, extending upwardly from the main frame 2. A trip arm 37 is fixed to said rock shaft 35 and extends upwardly between and above the plane of the track rails in the path,y

chine may be provided with suitable brush Y or belt pressure means common to such type of machines.

As soon as the can has'passed over and beyond the trip arm to again free the arm, it is quickly swung upward through the tension of a spring 38, one end fixed to the bracket 36 and its opposite end to an arm 39 on the rock shaft 35, and the stop arm is simultaneously lowered to stop the can after it has engaged upon the glue distributing roll 17.

For spot-gluing, the can under the wellknown practice of applying labels upon cans, which are not necessary to be sealed at the cover joint, the stop arm or iinger 19 is moved and sustained in a position at whichit will not engage the can. This can be done by unhooking the spring 38 from the arm 39. The trip arm will then swing downward by gravity, and the course of the can will be free'through the machine.
